It is for me, since it makes these newer compressors inaccessible to me.

I actually have a plug-in for JPEG2000 in Photoshop 5.0.2, but it has
never worked correctly.

Does JPEG2000 provide any type of scripting or executable code features
in the file format?

What about vice versa?  I could use a nice little converter that would
generate clean JPEG2000 files from a lossless format, such as, say,
TIFF.

I've written code, but I don't really have much of a development
environment set up at the moment.
